“I used to like ‘My Way,’ but after all the trouble, I stopped singing it,” he said. “You can get killed.”

The authorities do not know exactly how many people have been killed warbling “My Way” in karaoke bars over the years in the Philippines, or how many fatal fights it has fueled. But the news media have recorded at least half a dozen victims in the past decade and includes them in a subcategory of crime dubbed the “My Way Killings.”

The killings have produced urban legends about the song and left Filipinos groping for answers. Are the killings the natural byproduct of the country’s culture of violence, drinking and machismo? Or is there something inherently sinister in the song?
